Abstract

Multilayer film comprising at least a skin layer, a core layer and an inner layer,whereby the inner layer comprises a single site catalyst derived (SSC) random propylene ethylene copolymer having - a melting temperature (Tm) from 120°C to 144°C, - a content of units derived from ethylene in an amount of 1.5 to 6.0 wt.-%, - the melting temperature (Tm) fulfilling the following equation Tm < 156 °C – [5.2 x C2 content in wt.-%] °C wherein C2 content stands for the content of units derived from ethylene; and - a xylene cold soluble content (ISO 16152, 1st ED, 2005-07-01; 25°C) of preferably below 30 wt.-% wherein the multilayer film is free of phthalic acid esters as well as decomposition products thereof.
